If you're looking for something to read, or also if you're just interested for other reasons, I very much recommend checking out Greg Laden's Congo Memoirs — a series of blog posts where he reminisces on events that happened while he was working in Zaire (nowadays the Democratic Republic of the Congo) on a palaentological/archaeological expedition.
My friend Bwana Ndege (Mr. Bird) had visited the mouth of the Semliki the year before, from his home in Isiro. I saw him after the trip. He told me he saw some mighty big crocs where the Semliki emptied into the lake.
"How big were they?" I said.
"About this big," he replied, squinching his right eye down on his monocle, cigarette holder erect in the left corner of his mouth, his safari hat tilted back, his riding pants pressed and motorcycle boots shined, and his hands about 90 cm. apart. "... yes, I'd say about zeez big," playing up his native German accent a bit.
"Not even a meter long!?" I inquired inquisitively, knowing he was somehow pulling my leg, but not yet knowing what direction he was pulling it in.
"Absolutely. That much. About ninety centimeters distance I would say. ... (pause) ... BETWEEN ZEE EYES!!! ... Ha ha."
